Forensics Expert Talks About DNA Testing

By Maureen Kyle

(NEW ALBANY, Ind.) -- The grey sweatshirt found in David Camm's garage at the time of the murders put another man's DNA at the crime scene and raises new questions. WAVE 3's Maureen Kyle takes a closer look at how forensics detectives use DNA to determine how that sweatshirt ended up at the crime scene.

The grey sweatshirt spattered in blood was immediately taken to forensics labs for DNA testing right after the murders in September of 2000.

Specialists tested the blood and determined it belonged to the Camm family. But the unidentified DNA on the collar of the sweatshirt baffled detectives.

Now experts say it's clear the DNA is Charles Boney's, an ex-convict who admits he has a history of armed robbery and violence against women.

Andrea Reed works for the Kentucky State Forensics Lab, which is not working the Camm case. She admits it's difficult to determine who was wearing a piece of clothing unless there's a significant amount of DNA left on the material.

"Any place there's a lot of contact with the body. Obviously, sweat from the underarms, and you're actually rubbing the back in the neck."

Indiana State forensics experts found skin cells matching Charles Boney on the collar of the sweatshirt.

This means...that sweatshirt was not washed after Boney wore it.

Reed says "if you wash and dry clothing, it pretty much destroys DNA, but that's not always the case. With my own testing in our labs, I've seen semen will stick after testing. Blood would stick occasionally. Sweat would usually wash away."

Reed says DNA evidence will stick on clothing for an undetermined amount of time.

Boney told WAVE 3 he dropped the unwashed sweatshirt off at the Salvation Army three months before the murders.

The charity admits it doesn't wash the clothing it receives.

The unidentified DNA was just recently run through a national database. That's when the state got Boney's name as a match. Boney's nickname, "Backbone," was written on the collar of the sweatshirt, and he admits to WAVE 3 that the sweatshirt is his.
